MANUFACTURE OF RUBB ER DECOY-DUCKS.

SPECIFICATION forming part of Letters Patent N0. 349,315, datedSeptember 21, 1886.

Application filed February 2, 1886. Serial No. 1 90.609. (No model.)

To whom it may concern.-

Be it known that I, GEORGE H, NYE, a citizen of the United States, and aresident of Ohicago, county of Cook, and State of Illinois,

have invented new and useful Improvements in the Manufacture of RubberDecoy-Ducks, of which the following is a specification, reference beinghad to the accompanying drawings, illustrating the invention, in whichFigure I is a sectional elevation of one-half of the rubber shell of thebody, neck, and head of a decoy-duck manufactured on my improved plan,the neck being shown in position with the body, but not attached; Fig.II, a plan .or top view of the body of the decoy-duck complete, with thehead and neck removed. Fig. III represents a cross-section of one-halfof the shell of the duck as it is pressed into shape by dies. Fig. IVrepresents when cementing the shells together.

the form of the core for one-half of the shell body of the duck. Fig.Vis a transverse section of the two half-shells of the duck with thecores therein, and the dies in position, as Fig. VI represents the corefor the shell of one-half of the neck and head of the duck. Fig. VII isan inverted View of the head and neck of the duck. Fig. VIII is atransverse section of one'halt' of the shell of the head in position inthe dies as it is being pressed into shape.

This invention relates to the manufacture of decoy-ducks of rubber ofsuch thickness that they will assume their original forms after havingbeen put out of shape in the packing for shipment; and its natureconsists, so far as this application is concerned, in the method ofmaking the two half-shellsv of the body and those of the head and neck,and then uniting these halfshells to form the ody and head part of theduck, as hereinafter fully described and shown. I

A, Figs. I and III, representsa halfrubber shell of the duck after ithas been pressed into shape, as follows: Two dies, I, are formed inreverse counterparts to fit the longitudinal exterior of the duckdesired. The meeting faces of the dies being vertical on the middle ofthe duck, suitable inner forming-dies, L, are made to fit these reversecounterpart dies I, leaving spaces between them corresponding to thethickness of the sheet-rubber employed. The sheet-rubber is then cut inproper blanks and the blanks placed on the die I and pressed into shapeby the inner forming-dies, L, proper heat being employed, as'iscustomary in the manufacture of rubber goods. The surplus rubber is thencut away level with the face of the die and the half-shell of the bodyof the duck removed. Reverse counterpart cores F R are formed of sand,by any wellknown process, to correspond precisely with each reversecounterpart rubber shell, and placed inside thereof. The sections ofr'ubher, with the cores therein, are placed together, with suitablecement between their edges, and then put in dies N N, Fig. V,which havethe precise form of the die L and its reverse counterpart, and forcedtogether with some proper power by a screw-press, P, or other power, andthe rubber subjected to the usual heat for cementing the rubbertogether. The bodies ofthe ducks are then placed in water, whichdissolves the cores, which are washed out through a hole, D, which isformed by the core projections R. The head B and neck G are formed invertical longitudinal sections by dies, and cemented together overcores, inprecisely the same manner as the body of the duck is made, andthe two-part core run out at the hole E, which is formed by theprojections H on them. A halfcore, G H, for the head and neck, is shownat Fig. VI, and one section, B, of the rubber in the dies M K is shownat Fig. VIII.

There are other improvements in connection with perfecting thisdecoy-duck which are presented in a separate application of even dateherewith.

I do not claim a rubber decoy-duck, but the method of manufacturing thesame.

I claim as new and desire to secure by Letters Patent of the UnitedStates- In the manufacture of the heads and necks and bodies ofdecoy-ducks from rubber, the reverse counterparts A B G, formed in dieshavingsuitable contours, and the shells of rubber so formed filled withcores, respectively, and the rubber shells and cores subjected topressure in a two-part die having the contour of the duck to be formed,and the two shells cemented together and the cores removed,substantially as specified.
